Local Privilege Escalation Vulnerability Affecting X.Org Server For 18 Years
(www.phoronix.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What do you expect? X11 is in maintenance mode. Although I'll miss Polybar, I won't miss the protocol.
I think it's still valuable to document these things so that the users who insist on sticking with X11 can receive a healthy dose of this (replace diapers with vulnerabilities) when the proverbial shit hits the fan and it becomes as hackable as Windows XP

Is it? Afaik it very much is not
Well, freedesktop.org is now focused on Wayland (Xorg is not getting HDR, new synchronization protocols, or proper VRR (unless through XWayland), while Wayland is). RedHat RHEL marked Xorg as deprecated last year and will not even support it by next year (RHEL 10). KDE and GNOME also default to Wayland.
It is. That's why Wayland is being pushed so hard, it's a codebase that's actually maintainable, with hopefully some more modern design and engineering principles.
